1
00:00:00,000 --> 00:00:13,339
Music and sound effects.

2
00:00:13,374 --> 00:00:14,443
Green propellant to me is a way to

3
00:00:14,478 --> 00:00:16,507
reduce the cost, the

4
00:00:16,542 --> 00:00:17,867
program and over all

5
00:00:17,902 --> 00:00:19,659
mission costs for  attitude control for

6
00:00:19,694 --> 00:00:22,123
spacecraft  because we get rid of all of

7
00:00:22,158 --> 00:00:24,826
the hazards and environmental

8
00:00:24,861 --> 00:00:25,403
dangers associated

9
00:00:25,438 --> 00:00:26,538
with hydrazine. One

10
00:00:26,573 --> 00:00:27,563
of the great benefits,

11
00:00:27,598 --> 00:00:28,827
performance-wise with

12
00:00:28,862 --> 00:00:30,667
this propellant is the

13
00:00:30,702 --> 00:00:32,187
ISP on the engines is

14
00:00:32,222 --> 00:00:33,899
a little bit better, we

15
00:00:33,934 --> 00:00:35,130
are actually looking

16
00:00:35,165 --> 00:00:36,363
at a 40% increase in

17
00:00:36,398 --> 00:00:37,786
density ISP with it, with

18
00:00:37,821 --> 00:00:40,427
this type of propellant.

19
00:00:40,462 --> 00:00:41,403
Well with having this

20
00:00:41,438 --> 00:00:44,362
given tank volume that

21
00:00:44,397 --> 00:00:44,971
you don’t want to

22
00:00:45,006 --> 00:00:46,075
change, you are getting a

23
00:00:46,110 --> 00:00:47,419
40% increase in mission

24
00:00:47,454 --> 00:00:48,507
life with the propellant

25
00:00:48,542 --> 00:00:49,259
that’s in there; or

26
00:00:49,294 --> 00:00:50,299
you can bring down the

27
00:00:50,334 --> 00:00:51,419
size of the tank, put

28
00:00:51,454 --> 00:00:52,443
on more payload and

29
00:00:52,478 --> 00:00:53,675
things like that.  The

30
00:00:53,710 --> 00:00:54,843
real area we are trying to

31
00:00:54,878 --> 00:00:56,490
save money in is in

32
00:00:56,525 --> 00:00:58,362
the loading. In a sense

33
00:00:58,397 --> 00:00:59,483
you can take this stuff

34
00:00:59,518 --> 00:01:00,458
pour it into a funnel

35
00:01:00,493 --> 00:01:01,531
into a tank and cap it

36
00:01:01,566 --> 00:01:02,827
off. Of course we won’t

37
00:01:02,862 --> 00:01:04,139
be doing it that simply,

38
00:01:04,174 --> 00:01:05,179
right, but you could

39
00:01:05,214 --> 00:01:05,931
do that with this

40
00:01:05,966 --> 00:01:06,843
propellant. Whereas hydrazine

41
00:01:06,878 --> 00:01:08,059
is hydroscopic, it

42
00:01:08,094 --> 00:01:09,355
will pick up moisture as

43
00:01:09,390 --> 00:01:10,427
a contaminant, this

44
00:01:10,462 --> 00:01:11,803
stuff does not do that. It

45
00:01:11,838 --> 00:01:13,116
has a broader temperature

46
00:01:13,151 --> 00:01:14,778
range, it is easier

47
00:01:14,813 --> 00:01:16,923
to employ in the

48
00:01:16,958 --> 00:01:18,219
spacecraft because you know

49
00:01:18,254 --> 00:01:19,355
you can have wider

50
00:01:19,390 --> 00:01:20,570
temperature variations and

51
00:01:20,605 --> 00:01:21,691
not have issues with

52
00:01:21,726 --> 00:01:22,827
the propellant itself.

53
00:01:22,862 --> 00:01:24,683
So really looking at

54
00:01:24,718 --> 00:01:27,995
having enhanced capability

55
00:01:28,030 --> 00:01:30,747
for an ESPA class or

56
00:01:30,782 --> 00:01:32,123
a small sat ride-share

57
00:01:32,158 --> 00:01:33,307
payload that comes off

58
00:01:33,342 --> 00:01:35,499
at that point in time in

59
00:01:35,534 --> 00:01:37,019
the mission. We are adding

60
00:01:37,054 --> 00:01:38,395
propulsive capability

61
00:01:38,430 --> 00:01:39,835
to that and allows a

62
00:01:39,870 --> 00:01:40,827
lot of other technologies

63
00:01:40,862 --> 00:01:41,787
to be demonstrated that

64
00:01:41,822 --> 00:01:43,003
would not otherwise be.

65
00:01:43,038 --> 00:01:44,155
Another advantage of

66
00:01:44,190 --> 00:01:45,099
having this is enhancing

67
00:01:45,134 --> 00:01:46,557
the de-orbit capabilities

68
00:01:46,592 --> 00:01:48,315
of this spacecraft,

69
00:01:48,350 --> 00:01:50,266
you know we have a 25 year requirement,

70
00:01:50,301 --> 00:01:51,787
well now by having this

71
00:01:51,822 --> 00:01:52,874
propulsion system on

72
00:01:52,909 --> 00:01:54,011
there we can potentially

73
00:01:54,046 --> 00:01:55,404
go into higher orbits

74
00:01:55,439 --> 00:01:56,891
and do different types of experiments

75
00:01:56,926 --> 00:01:58,283
we couldn’t have before,

76
00:01:58,318 --> 00:01:59,771
then bring it in and meet

77
00:01:59,806 --> 00:02:01,467
the 25 year de-orbit

78
00:02:01,502 --> 00:02:03,083
requirement for orbital

79
00:02:03,118 --> 00:02:04,395
debris. The costs are

80
00:02:04,430 --> 00:02:05,595
going to be very similar

81
00:02:05,630 --> 00:02:06,586
if not the exact same

82
00:02:06,621 --> 00:02:07,626
and we are saving a ton

83
00:02:07,661 --> 00:02:09,562
of money on the handling,

84
00:02:09,597 --> 00:02:11,707
loading of this stuff

85
00:02:11,742 --> 00:02:12,843
and a lot of the safety

86
00:02:12,878 --> 00:02:13,899
issues associated with

87
00:02:13,934 --> 00:02:14,827
hydrazine. Right now

88
00:02:14,862 --> 00:02:16,283
you have to suit up in

89
00:02:16,318 --> 00:02:17,723
full bunny suits with AC

90
00:02:17,758 --> 00:02:19,451
tubes to keep the clean

91
00:02:19,486 --> 00:02:21,404
air flowing. You know

92
00:02:21,439 --> 00:02:22,427
you put on a mask here,

93
00:02:22,462 --> 00:02:23,482
like you’re at the

94
00:02:23,517 --> 00:02:24,186
dentist office to make sure

95
00:02:24,221 --> 00:02:25,562
you’re not getting any

96
00:02:25,597 --> 00:02:26,698
contaminants and handle

97
00:02:26,733 --> 00:02:27,787
the stuff with gloves in an open room

98
00:02:27,822 --> 00:02:30,171
environment.  Lot safer.

99
00:02:30,206 --> 00:02:31,466
And the real savings would

100
00:02:31,501 --> 00:02:32,843
be getting rid of all

101
00:02:32,878 --> 00:02:34,283
that processing at the

102
00:02:34,318 --> 00:02:35,403
launch facility. Taking

103
00:02:35,438 --> 00:02:36,683
the propellants back,

104
00:02:36,718 --> 00:02:37,755
loading them at the

105
00:02:37,790 --> 00:02:39,355
spacecraft manufacturers

106
00:02:39,390 --> 00:02:40,315
and then we can ship

107
00:02:40,350 --> 00:02:41,146
these. We are launching

108
00:02:41,181 --> 00:02:42,028
in three years, right

109
00:02:42,063 --> 00:02:42,939
now our target vehicle

110
00:02:42,974 --> 00:02:43,995
is STP2. The first

111
00:02:44,030 --> 00:02:46,171
portion of the program is

112
00:02:46,206 --> 00:02:47,467
focused on the work

113
00:02:47,502 --> 00:02:48,971
that Ball is doing with

114
00:02:49,006 --> 00:02:50,299
Aerojet, maturing the

115
00:02:50,334 --> 00:02:51,227
technology of the engines.

116
00:02:51,262 --> 00:02:52,923
Once Aerojet has completed

117
00:02:52,958 --> 00:02:54,251
development of this

118
00:02:54,286 --> 00:02:55,387
technology, which

119
00:02:55,422 --> 00:02:57,195
includes tanks, valves and

120
00:02:57,230 --> 00:02:58,379
thrusters, they are

121
00:02:58,414 --> 00:03:01,146
going to build that up as

122
00:03:01,181 --> 00:03:03,003
a payload assembly.

123
00:03:03,038 --> 00:03:03,930
Ball gets integrated, we

124
00:03:03,965 --> 00:03:04,811
do the environmental

125
00:03:04,846 --> 00:03:05,979
testing and final checkout

126
00:03:06,014 --> 00:03:08,123
at Ball. If we can

127
00:03:08,158 --> 00:03:09,371
really pull it off, we

128
00:03:09,406 --> 00:03:10,443
will fuel it up at Ball,

129
00:03:10,478 --> 00:03:11,947
then we will ship it
